Laptop came with Endless OS (Linux) and everything was working fine. Formatted the hard disk and installed Windows 10 and everything is fine. Installed Ubuntu as dual boot but can't connect with neither wifi nor ethernet. Have to use tethering via phone to have internet. Without it, laptop says ethernet network disconnected even though it is still plugged in and I can't find the wireless.

Ran this

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info

and here's the output

########## wireless info START ##########
